hi, i am new to using linux, i have a problem i dont understand, ill try to explain my situation as best as possible

Well i got my server running not too long ago and ive had fun messing with PHP and mysql and things like that but then it came time to buy a .com, so i bought www.thegoshem.com, feel free to check it out, anyways, after that i said hey, i want my email to be goshem@thegoshem.com,

backtracking a bit
i previously was using dyndns.org and goshemx.homelinux.com
